To all whom it mag concern:

Be it known that I, EDWIN C. WEISGEB- BER, captain, Corps of Eng, U. S. A., a citizen of the United States, stationed at Washington, D. C., have invented an Improvement in Colored Smoke,"of which the following is a specification.

The invention. described herein may be used by the Government, or any of its oflicers or employees in prosecution of work for the Government, or by any other person in the United States, without payment of any ro alty thereon.

e invention relates to colored smoke, formilitary or other purposes, and has particular relation to smoke that is red.

The smoke producing composition is made up of the following ingredients, with substantially the proportions given.

30 parts potassium chlorate, parts lactose,

40 parts ammonium iodid, parts iodin.

Each of the ingredients is ground to pow der separately, and bolted through ordinary bolting cloth. They are then well mixed by pouring from one receptacle to another, instead of stirring which might be dangerous, and the finished product will give a smoke of great volume and very dense. The proportions may be slightly'varied'to suit conditions, as more chlorate will cause the product to burn faster, and more idodin will cause the smoke to be denser.

What I claim as my invention is:

1. A colored smoke. producing composition comprising potassium chlorate, lactose,

ammonium 1od1d, and iodin.- v

2. 4 colored smoke producmg COIIIPOSI- tion comprising in substantially the proportions following:

Potassium chlorate parts. Lactose 15 parts. Ammonium iodid 40 parts. Iodin 25 parts.
